From dc5e20ae1f8a7c354dc9833faa2720254e5a5443 Mon Sep 17 00:00:00 2001 From: Nirmoy Das Date: Fri, 13 Dec 2024 13:24:14 +0100 Subject: [PATCH] drm/xe: Use non-interruptible wait when moving BO to system MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Ensure a non-interruptible wait is used when moving a bo to XE_PL_SYSTEM. This prevents dma_mappings from being removed prematurely while a GPU job is still in progress, even if the CPU receives a signal during the operation.
